Definitions

  • Patent Literature 1 JP 2014-113256 A
  • an object of the present invention is to provide: an endoscopic device for constituting an endoscopic system that is smaller in size, lighter in weight, simpler in configuration, or lower in cost than the conventional systems and that does not require a higher skill or practice to use the system; and an endoscopic system including the endoscopic device.
  • the accommodation section of the rigid laparoscopic device may also serve as a grip member which can be gripped to hold the optical viewing tube.
  • accommodation section may be provided with a valve operating section used to open and close a valve of the gas cylinder.
  • the user can perform the operation for opening or closing the valve device, even in a case where the gas cylinder is accommodated in a form that does not allow the user to touch the main body of the gas cylinder, for example. This makes it possible to enhance freedom of selection of the accommodation form for the gas cylinder.
  • optical viewing tube may be integrally couplable further with a display device configured to display the image having been converted into the electric signal by the converting device.
  • the endoscopic device is assumed to be sterilized before the endoscopic device is packed after being manufactured as medical equipment. Also, endoscopic device is assumed to be sterilized for reuse in a medical site.
  • the accommodation section that is sterilizable, it is possible to reduce the burden of securing cleanliness of the endoscope.
  • the accommodation section may be made of a material excellent in heat resistance and/or chemical resistance, and may be configured to have high airtightness, high water-tightness, and high pressure resistance.
  • the rigid laparoscopic device 111 includes a light guide cable 122 (e.g., an optical fiber cable) that is an illumination optical system, an objective lens 123 that is an observation optical system, an optical viewing tube 121 incorporating relay lenses 125a to 125d for transmitting an image, an eyepiece 171 connected (e.g., by a screw) to a base end of the optical viewing tube, and an accommodation section 131 including a light source device section 132 and a gas feeding section 133.
  • a light guide cable 122 e.g., an optical fiber cable
  • an objective lens 123 that is an observation optical system
  • an optical viewing tube 121 incorporating relay lenses 125a to 125d for transmitting an image
  • an eyepiece 171 connected (e.g., by a screw) to a base end of the optical viewing tube
  • an accommodation section 131 including a light source device section 132 and a gas feeding section 133.
  • the eyepiece 171 is provided with an eye lens 172.
  • a user looking into the eyepiece will see an image taken by the objective lens 123 at a tip end of the optical viewing tube and then transferred to the eyepiece by the relay lenses 125a to 125d.
  • the specification of the battery to be used is not particularly limited.
  • the battery to be used may be either a primary battery or a secondary battery.
  • the light source switch 143 is provided to switch between ON and OFF of the illumination.
  • the light source switch 143 may be omitted, and the illumination may be configured to be turned ON continuously after the battery is set.
  • the rigid laparoscopic device 111 may be configured to be disposable.
  • the gas cylinder and/or the battery may not be replaceable, and thus the accommodation section 131 may not be openable via the lid member 135, for example.
  • the rigid laparoscopic device 111 may be made of an inexpensive resin (e.g., polyethylene), and may not necessarily have high airtightness or waterproofing property.
  • the rigid laparoscopic device 111 at a quite low cost.
  • the whole of the rigid laparoscopic device 111 may be configured to be disposable.
  • part of the rigid laparoscopic device 111 for example, only the accommodation section 131 may be configured to be disposable.
  • the light source device accommodation section 232 has an accommodation-section-side connector 235 for connection with the optical viewing tube 221.
  • the accommodation-section-side connector 235 is detachably connected to a main-body-side connector 223, which is provided to the optical viewing tube 221.
  • Means for the connection is not particularly limited.
  • the connection may be achieved by engagement between screws, i.e., a male screw that serves as the accommodation-section-side connector 235 and a female screw that serves as the main-body-side connector 223.
  • An upper portion of a main body of the gas cylinder 251 has a push button 254 which is configured to operate interlockingly with a valve device in the cylinder and which is provided with a nozzle 255. Pushing down the push button 254 opens the valve device incorporated in the main body, thereby allowing carbon dioxide gas filled in the cylinder to be fed into the abdominal cavity of the patient through the nozzle 255, the air feeding tube 256, and the pneumoperitoneum needle 257.
  • the rigid laparoscopic system according to the present invention is not necessarily limited to laparoscopic surgeries for human. That is, with the rigid laparoscopic system according to the present invention, an operator can move rapidly even while holding the rigid laparoscopic system, and therefore the rigid laparoscopic system according to the present invention is applicable also to treatments for animals that move unpredictably. Hence, the rigid laparoscopic system according to the present invention is applicable to laparoscopic surgeries for pet animals and domestic animals, such as dogs and cats.
